Here, then, lies the answer to how to tell whether some developer you’ve just met (or are interviewing) is serious about their craft in five seconds flat: borrow their device, and triple-click the home button. If you don’t hear “VoiceOver on”, or get prompted about VoiceOver, consider that −3 points on the Steve Test.

After spending the last third of this week’s podcast yelling about this, it’s good to know that I’m not the first to suggest that all iOS developers map triple-tap-home to toggling VoiceOver.

Since I made that change on my primary iPhone and iPad, I don’t think I’ve shipped a single major VoiceOver problem in my apps. It became so much easier to test that I ended up testing with VoiceOver frequently throughout development, not just at the end of each version if I’d happen to remember.

If you need a quick intro to supporting VoiceOver, watch the “Accessibility for iOS” WWDC session video. It’s quite easy.
